Axes lines ... Uninvited to the Party! and "Failed to Save File" REALLY :-/

Hey guys, Long time SU user here. I’m having issues with SU17. These were never issues for me in SU15.
#1. Failed to save file appears in all my models that were created in 15 and now being accessed and worked on in 17.
#2 and more annoying… My axes lines (and guides) turn on all the time whether I want them to or not. If I select a style option… they turn on, If I create an animated scene they show up when playing back. Its ridiculous and makes a presentation to clients impossible.
I’m not sure if its because they are large files (192.5 MB) and originally created in 15? I haven’t built any sizable models from scratch since upgrading to 17.
